Hi, Thanks for writing in. Patients might have difficulty in ejaculation after taking treatment for testicular cancer. This is usually for a short duration and patients will improve with time. If you both plan to have children then it is best to first get a semen analysis done and then consult a fertility clinic to know the probabilities of have a child in the natural way. If on few attempts you are not able to have a pregnancy with your partner then artificial reproductive techniques might help. In present days there is a lot of medical advancements which might benefit you.
